.Be it-known that I, SAMUEL I citizen of the United States, residing, at

Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in.

Phosphorus Compounds; and I do hereby declare the following to bea-full, clear and exact description of the invention, such as willenableothers skilled inqtheart to which.

it appertains to make and usethe same.

This invention, relates; generally, to a novel phosphorus composition,and to a method or process of producing thesame. v

The preparation and use of compositions or .products containingphosphorus as an essential ingredient for industrial and other purposes(as in the art of manufacturing matches, pyrotechnical devices, andsimilar products) entails the disadvantage that, in the presence of air,the'phosphorus by oxidizing gives off irritating acid fumes, which notonl have a very injurious effect upon the health of the workmen engagedin preparing and handling the same, but are also very unpleasant andannoying.

I have discovered that the usual giving off of acid fumes due tooxidization of the phosphorus may be prevented without detriment to theeffectiveness of the phosphorus for industrial purposes; therefore,this'invention has for its principal object to provide a novelnon-fuming phosphorus composition, and, as a further object, to providea novel method or process'of producing such composition.

To the above-stated ends this invention comprises a compositionconsisting of an admixture of phosphorus with certain organic bases ofhigh boiling point, said organic bases being of a nature adapted to takeup or absorb the fumes of phosphoric oxide as formed and to neutralizethem, while serving at the same time to protect the phosphorus againsttoo ready an oxidization.

As an example of the character of the organic bases, adapted to servethe stated purposes, may bev mentioned a-naphthylamine anddimethylaniline, although I do not wish to confine the inventionentirely to the use of these particular substances, but broadly claimthe use-of any organic base or bases capable of combining withphosphoric oxide fumes.

' Application filed December 22, 1921. Serial No. 524,256;

Broadly stated, the novel non-fuming phosphoruscomposition consists ofan ad-.

mixture of 82 parts of phosphorus, 2parts gofa-naphthylamine andt partsof dimethylaniline. To mask-the slight odor of the organic bases a smallquantity of a fragment essential oil, such as oil of sassafras, may beadded to the composition.

The method of producing composition is as follows i For COIIVGIHGDQG ofadmixing the phosphorus smelted by warming. I sometlmes add a smallquantity of sulphur to the phosphorus, which, tends to maintainthephosph'orus inliquid condition, although the -.compos1tion-may bemade without the-:sul:

hur if desired. When the phosphorus is iquefied I add the liquid organicbases,

a-naphthlyamine and dimethylaniline,

.More in detail, and as an illustration of a practicalcompositionforrmatch making purposes and the like, having theingredients combined in relative proportions adapted to give generallysatisfactory results, I take 32 parts of phosphorus and melt the sametogether with 5 parts of sulphur after the liquefied hosphorus "is thusproduced, the same is a lowed to cool, whereupon I add to and intermixtherewith 2 parts of a-naphthylamine and 4: parts of dimethylaniline.The resulting mixture or composition can be preserved without anydevelopment of white fumes, or so called phosphorus odor, such fumesbeing absorbed as soon as formed by the organic bases used, to wit, thea-naphthylamine and the dimethylaniline.

I do not wish to confine myself to the use of the two organic baseshereinbefore mentioned, but may use other organic bases of sufiicientlyhigh boiling-point as not to vaporize too readily while in admixturewith the hosphorus. nor do I wish to confinemyse' f to the exactproportions of the ingredients of the composition since in this respectmore or less variation'is possible.

The composition such as I have described may be used by itself or inadmixture with thylamine and dimeth laniline'.
